weird whirring/whistling coming from engine

[newshofan]

ok yea i have noticed this noise in the past but recently it has gotten worse and is now constant it is coming from the passenger side of the engine. im gonna say around the belt areas. Does anywone have any ideas? I do need my front 60k done. could this be the problem?

Its your Turbocharger!












Or could be the idler pulley. Does it make the noise all the time or just when your accelerating?

lol. wish it was the turbocharger...lol...and yes it does it all the time. it started after i hit a big dip in a parking lot. along with my anitfreeze leak. ive yet to check that one out it has slowed. so the idler pulley has a lot to d with this? and can it effect gas mileage

Try taking off your serpentine belt and manually spin each pulley to see where the noise is coming from - it could just be a worn bearing in one of your pulleys. Spinning each one by hand will give you a better idea of the culprit than standing next to the car with the motor running trying to pinpoint it.

Take the alt belt off the engine, start the car . Is the noise still there ?
Do the the same with the WP/ PS belt . Same question ?
Spin all the pulleys by hand . After that id check the timing belt tensioner.

If I read your other post right you mention you go from hot to cold on the temp gauge because you have air in the system. It could most likely be the water pump trying to pull air around the cooling system. You need to BLEED your cooling system before you destroy cooling system components(a.k.a. water pump).

ok yea ive got the antifreeze problem about fixed i just have to find where its leaking underneath the enigine i havent had time to check much. i know my battery light is on and i tested the battery. Im thinking may be the alternater.but wont know for sure till i check it out.

 

[newshofan]

is it possible it could be the pully on my water pump i glanced at the pulleys with the car running and it is wobbling a tad

It's possibly your alternator making the noise especially since your battery light is on.

ok i dont thinkits the alt because my battery light is no longer on. ik thinking water pump now
